I've recently purchased a tail tidy. Thanks WB

Before I take the hacksaw to my 4 week old XTX I want to purchase a new or nearly new undertray to keep safe for when I return the bike back to standard. I've done a few searches on the forum and I know somewhere there is a thread with genuine Yamaha XT660 part numbers.....but I can't find it. Can someone give me the link, or just the part number for the undertray?

Many thanks

Lee
